Grass clippings mulch

[Matt.]

What veggies like this as a mulch? I already use it on my spuds as it supposedly helps against scab. I cut quite a lot and its getting difficult to match brown with green in the compost bin.

have heard it helps to deter carrot fly.as yet never used it~our grass clippings often contain grass seed among other perrenial cuttings~little worried having got rid of the couch grass etc reintroducing it via the mulch?
